Accuphase P-300S Stereo Power Amplifier

Accuphase Laboratory, Inc. (known initially as Kensonic Laboratory, Inc.) is a Japanese, Yokohama-based high-end audio equipment manufacturer founded by former Kenwood engineer Jiro Kasuga in late 1972.

Use the Accuphase c-200S Stereo Control Center as a preamp to work with the Accuphase P-300S Stereo Power Amplifier. Here at Audio Image we also have the Accuphase Monophonic Power Amplifier M-60 (Monobloc) pre-owned for demo.
